When Satchmo sings his 1968 hit "What a Wonderful World" you believe him utterly, knowing full well that his road in life was not an easy one. In these live small-group sessions from the 1960s, Armstrong shines with some of his most beloved repertoire, including "Mack the Knife," "Cabaret," "C'est si bon," "After You've Gone," "Indiana," "When It's Sleepy Time Down South," and "On the Sunny Side of the Street."
